W221 ANDROID touchscreen...




Install 3.5mm jack on wires coming from the head unit
give the power supply some power
connect speakers to power supply
install behind head unit

Oh and yes it would be that easy white/black and red/black and you should have some sound.
Today I thought I had a brilliant idea, I have some Logitech USB speakers which has no external power supply (power from USB only), so I hooked them up to one of the USB ports hoping it would work, cause they have really good sound considering their size. When I connect them I immediately get the blue power light. But no sound. I can even press the volume adjusters on the speakers and it shows up that it is changing volume on the screen. But no sound. Could not find anywhere to tweak it in the software either, but then again I am not familiar with Android. Any ideas if this should be fixable in the software somewhere? It would by far be the easiest and best solution for me, considering I can't get sound through the cars system itself..

I have several of these in my house and garage, they're pretty awesome and durable. You should be able to connect it via Bluetooth to the Android unit.https://www.jbl.com/bluetooth-speake...ck-USA-Current

So - I got the MB star back as "BOOT LOGO" in the general settings, but when trying to update start screen to get the "android" startup screen away(which appears after the MB star has been there for some seconds), going to "software version" then settings and code 12345678 and pressing the upper button in chinese, it just stays with the spinning "wait" icon forever. I waited at least 10 minutes before just powering off, and restarting. Then nothing was changed. Do I need to get the file and put it on a USB? I tried to google to find something, but couldn't find anything. Anyone have a link or something to the "Mercedes-Benz" and "AMG" startup screens, if that's what's needed?
Not new to cars, not new to car forums, but this thread is full of so much information that it was confusing as hell reading thru it as it jumped around.

I have a 2007 s550 4matic..it has ABSOLUTELY no aux input functionality, as I started looking and the dealer said I have nothing..
It also does not have the Mercedes dongle installed for factory Bluetooth phone connection.. It does have that connector in the co sole tho of course.
My questions are :
Will this work properly with my feature level harness etc?
Will this allow me to connect the screen via Bluetooth to my android phone and stream audio thru the entire vehicle sound system.. Spotify Etc?
Do I have the option of ALSO using a Bluetooth adapter in the USB to plug in an older ipod as a storage device
Are there any additional parts or labor that would need to be purchased or carried out in order to install into my year vehicle
My installation guy will need quite a bit of clean info or he's not gonna take the install job I'd not think.. Especially now that I hear. It has no manual?

Your help is wildly appreciated. I plan to make my order thru Chris this week of I can solidify the above info.

- Yes, you can play music from a phone.
- Depends on the iPod, but you can simply use a flash drive with all your music...no need for an iPod.
- Yes, look at my diagram. You will need a GPS antenna splitter if you want to use the stock GPS antenna.
- No manual. Actually it comes with 0 instructions, not even a pinout, as it's supposed to be plug and play. However, now that things have been figured out, it should be easy to install.
